INTRODUCTION AND GENERAL OVERVIEW Thank you for your purchase of an APR-5000-DZ Array Package Rework System. Each unit has been inspected thoroughly by OK International prior to shipment, and with proper maintenance will give you years of reliable performance. This user guide is a valuable resource. It explains the systems options, features, specifications and the correct operation of your APR-5000-DZ Array Package Rework System. If any problems should occur during setup or operation of your system, contact OK International s Technical Service Department or you may contact your local Representative or you may email us at support@okintl.com. The APR-5000-DZ Array Package Rework System provides both accurate component placement and specifically tailored reflow profiles (through OK International patented single component Micro Oven ) in one user friendly, single platform rework system. The challenges of Array Package Rework, and the inability to easily inspect placement accuracy (with BGAs in particular), call for a solution that allows for simultaneous viewing of PC board pads and component pads or balls for accurate placement. The APR-5000-DZ fills this need with quick, accurate placement through the use of an optical system employing dual image overlay technology. The image of the BGA solder balls is overlaid with that of the PC board pattern. The image is viewed on the computer monitor and the micrometers permit fine X, Y and Theta adjustment at up to 27X magnification. Finally, the part is placed and the vacuum is released automatically. After accurate component placement is achieved, the vacuum pickup tube is automatically retracted and the reflow nozzle is lowered into place. At this point, the component is subjected to a 5 zone, full convection reflow profile, specifically tailored to the requirements of that particular PCB, device and solder paste. Accurate duplication of original oven reflow parameters is achieved. During the course of the reflow profile, source temperatures and time intervals can be modified On the Fly, eliminating the need to wait for the current profile to terminate before modifications can be made. Precise solder joint temperatures are measured and displayed on a real time graphical display, thus providing the necessary data to accurately and easily establish the optimum reflow profile for each particular application within minutes. www.okinternational.com Page 10 of 124 7000-1850, Rev.

GETTING STARTED What is a Process? A Process is a set of parameters or settings, defined by the user. The machine follows the process parameters to complete a placement or removal of a device or component from a PCBA. These parameters include temperature profile, airflow, and nozzle positions (head height). What is a Profile? A Profile is a set of temperatures and associated durations defined by the user for a particular device, component, and PCBA. To begin using your APR-5000-DZ system you will need to develop a Process, so we will discuss Process Setup first, followed by Process Run and finally System Setup. Process Setup Click on Process Setup In Process Setup, one of the following options can be chosen: New Removal Process Setup mode for developing a new removal process for shields, BGA, CSP, and micro-smd components. New Placement Process Setup mode for developing a new placement process for shields, BGA, CSP, and micro-smd components. Modify Existing Process Setup mode for modifying an existing placement or removal process for shields, BGA, CSP, and micro-smd components. Manual Manual mode allows the user to import existing thermal plots and operate the APR-5000-DZ manually. Manual Mode is initially disabled. Enabling Manual Mode is discussed in the System Setup section. www.okinternational.com Page 33 of 124 7000-1850, Rev. C

New Removal Process This section explains how to develop a New Removal Process. Click on New Removal Process and then click Next. The machine will initialize and the following screen will appear. This screen allows the user to include information about the component and PCB being reworked including, Chip Package, Component Reference, and PCB Description. Simply type the information in the fields provided. This screen also includes an Instruction button. The instruction button allows the user to attach a file in PDF format to a process. These instructions can be instructions, notes, or reference photographs for the operators to follow during a Process Run. When the process is run the selected PDF file will automatically appear on screen. To use the Instruction button click on Instruction and open the desired PDF file from the drop down menu. www.okinternational.com Page 34 of 124 7000-1850, Rev. C

The PDF file will be displayed. Select Next to continue. In this window, an option to enter information is prompted. It is recommended the Yes button be selected and data be entered in each of the three fields. This information will be displayed in Process Run when this particular process file is opened. After entering the required data, click Next. Selecting Yes. Information input into User Prompt Cup Part Number and Nozzle Part Number will be displayed below. www.okinternational.com Page 35 of 124 7000-1850, Rev. C

Pull out the camera to make vision adjustments. As prompted, center the vacuum tube (nozzle) to the component using the X/Y buttons on the head and move the head so the vacuum nozzle is centered over the component. If necessary, use the X/Y micrometers on the base to make fine adjustments. Using the zoom slider bar, zoom in on the component to the desired magnification. Focus the image of the component using the focus slider bar. Use the down action buttons to lower the head until the vacuum nozzle is in focus. The speed of the head can be controlled with two options, Coarse and Fine. Coarse allows the head to move in a slow steady speed. Fine allows the user to step the head up and down in one-thousandth inch increments by clicking on Fine and adjusting the fine slider bar to the desired increment. Use the top and bottom lamp slider bars to adjust the lamp intensity to get a good view of both the component and the vacuum nozzle as seen in the example below. Component to be reworked Vacuum Nozzle www.okinternational.com Page 36 of 124 7000-1850, Rev. C

Click Next and return the camera back to the Home position as prompted. The user will be prompted to set the Reflow nozzle height. IMPORTANT All movements are recorded during Process Setup. As a result, any and all mistakes will appear in the Process Run. A way to avoid editing Process Setup programs each time an error is discovered is by clicking the Enable operator control during process run. This will allow the end user to modify the programmed height in Process Run. Press the down action buttons. The head will go down quickly until the nozzle is approximately 1.5 (38mm) above the PCB and then automatically decelerate to a slower speed. The head will continue to go down until the nozzle is approximately 0.5 (12.5mm) above the PCB; at this point the user must click on Fine and step the head down in increments set by the slider bar. After the Reflow nozzle touches the PCB, click Next. www.okinternational.com Page 37 of 124 7000-1850, Rev. C

The user will be prompted to set the Reflow nozzle height again. This is known as a back step, the back step raises the head to provide the extra clearance needed should the PCB flex upward while it is being heated. The user has the option to include a back step in the process by checking the Use this step check box or omitting the back step by leaving the check box unchecked. To set the back step height, raise the head in small increments by pressing the up action buttons just until the vacuum level indicator drops. Raise the head until vacuum level drops. Nozzle has been raised above the PCB www.okinternational.com Page 38 of 124 7000-1850, Rev. C

When done with adjustments, press Next. In Lift, the option to lift the component during the removal process is provided. This option was designed to allow for four distinct methods of lifting the component from the PCB. Retract vacuum tube Retracts only the vacuum tube. Designed to minimize adjacent component heating that may occur after removal. Raise head Raises the entire head approximately 0.25 (6.35mm). Raise head high Raises the entire head approximately 4 (101mm). Designed for use with high I/O removable such as large BGA components or CBGA. Tweezers Nozzle Raises the entire head approximately 0.25 (6.35mm) using the optional Tweezers Nozzle. Designed to rework components with limited or no surface area such as package-on-package BGA, sockets, connectors, potentiometers, inductors and even through-hole parts. Click Next after selecting the desired lift method. It is now time to create the temperature profile. Two buttons are available for selection: Start and Cycle Advance. Start - Starts the profile. After clicking on the Start button it will change to a Stop button. Clicking on the Stop button will abort the profile. Cycle Advance - allows the end user to cycle to the next zone. www.okinternational.com Page 39 of 124 7000-1850, Rev. C

While the profile is running the user can change the temperatures in each zone by using the Click and Drag method described on pages 29 and 30 of this User Guide. Once the profile has been completed click Next. As prompted raise the head to the home position by pressing the up action buttons. As prompted click Next to release the component. Note: The component should be at the temperature set in the cooling zone (zone 5) before it is released. The cooling time in the cooling zone should not be less than 100 seconds. If the cooling zone is set incorrectly be careful the component can be hot when it is released. After the component is released the user will be prompted to save the process. Save the process in the desired location. www.okinternational.com Page 40 of 124 7000-1850, Rev. C

After saving the process you will be taken back to the home page. The New Removal Process is now complete. www.okinternational.com Page 41 of 124 7000-1850, Rev. C

New Placement Process This section explains how to develop a New Placement Process. Click on New Placement Process and then click Next. The machine will initialize and the following screen will appear. This screen allows the user to include information about the component and PCB being reworked including: Chip Package; Component Reference; and PCB Description. Simply type the information in the fields provided. This screen also includes an Instruction button. The instruction button allows the user to attach a file in PDF format to a process. These instructions can be instructions, notes, or reference photographs for the operators to follow during a Process Run. When the process is run, the selected PDF file will automatically appear on screen. To use the Instruction button click on Instruction and open the desired PDF file from the drop down menu. Click Next to continue. www.okinternational.com Page 42 of 124 7000-1850, Rev. C

In this window, an option to enter information is prompted. It is recommended the Yes button be selected and data be entered in each of the three fields. This information will be displayed in Process Run when this particular process file is opened. After entering the required data, click Next. Select Yes. Information inputted into User Prompt, Cup Part Number, and Nozzle Part Number data will be displayed below. After entering the required data, click Next. The next window prompts the user to choose a pick-up method. Three different pickup methods are available. Component pick up - Designed for use with the adjustable centering nest. Although not preferred, this option also allows the user to prepare the rework site with liquid flux instead of gel flux or solder paste. Note: Liquid flux from flux pens etc. is not recommended for convection rework, the flux dries up quickly and becomes inactive during convection rework applications. www.okinternational.com Page 43 of 124 7000-1850, Rev. C

Pickup with paste - Designed for use with the OK International component stenciling plate. This method along with the correct stencil allows the user to recreate OEM standoff height. This process is preferred over both flux methods. Pickup with flux dip - Designed for use with OK International Dip Transfer Plates or Blocks, this process allows the user to transfer gel flux onto the solder balls only, increasing success rate and minimizing the amount of flux residue. Component Pickup Select Component Pickup and click Next. Pull out the camera as prompted. Place the component in the centering nest and place the nest on the centering fixture. Use the thumbscrew to adjust the size of the centering nest to accept the component being reworked. Be careful not to over tighten the thumbscrew or the vacuum nozzle will not be able to lift the component from the nest. Insert the centering nest over the pins on the centering fixture. www.okinternational.com Page 44 of 124 7000-1850, Rev. C

To set the component pick up height, use the down action buttons to lower the head until the vacuum nozzle comes in contact with the component. Vacuum nozzle is in contact with the component. Click Next to continue As prompted press the up action buttons to lift the component from the centering nest. When the head stops at the home position remove the centering nest and push the centering fixture back. Be careful not to bump the component while removing the centering fixture. Click Next to continue. www.okinternational.com Page 45 of 124 7000-1850, Rev. C

The next screen will prompt the user to zoom in on the component and adjust the focus. Use the camera and lighting controls to obtain a clear image of both the PCB and component. The following sequence is an easy way to get a clear image. 1. Zoom in on the PCB. 2. Raise the bottom lamp intensity to the maximum. 3. Lower the top lamp intensity to the minimum. 4. Focus on the PCB. 5. Lower the bottom lamp intensity to the minimum. 6. Raise the top lamp intensity to the maximum. 7. Use the down action buttons to lower the component until the solder balls are in focus. Note: Do not use the focus slider bar to focus the component. The focus slider bar is only used to focus on the PCB. www.okinternational.com Page 46 of 124 7000-1850, Rev. C

If the images are not aligned correctly use the X, Y, and Theta adjustments to align the component with the layout on the PCB. Component is miss-aligned with the PCB layout. Component is aligned with the PCB layout. www.okinternational.com Page 47 of 124 7000-1850, Rev. C

After you are satisfied with the component and PCB alignment click Next and return the camera to the home position as prompted. Press the down action buttons. The head will go down quickly until the nozzle is approximately 1.5 above the PCB and then automatically decelerate to a slower speed. The head will continue to go down until the nozzle is approximately 0.5 above the PCB. At this point the user must click on Fine and step the head down in increments set by the slider bar. Note: To avoid problems with crushed solder balls it is recommended to use increments of 10 mils or less while lowering the component to the PCB. Lower the component just until it touches the PCB. To prevent the component from moving when it is released from the vacuum pick-up tube it is recommended to set the Puff Off Time. www.okinternational.com Page 48 of 124 7000-1850, Rev. C

Puff Off Time Puff Off Time is an amount of time, in milliseconds. A puff of air is blown out the end of the vacuum pick-up tube for this duration to gently release the component without moving it. Set Puff Off time according to the recommendations below. Component Size Puff Off Time milliseconds 1mm 3mm 120 Small CSP 200 BGA 27mm 35mm 250-500 Larger than 35mm 750-1000 Note: These are recommendations only; it may be necessary to experiment to find the best Puff Off Time for your application. Click Next to continue. Use the action buttons to set the Reflow nozzle height. Note: The reflow nozzle does not have to come in contact with the PCB. An alternative safe method is to leave the nozzle 2-3mm above the PCB; this method may reflow adjacent components but will not blow them off the PCB. www.okinternational.com Page 49 of 124 7000-1850, Rev. C

Click Next to continue. It is now time to create the temperature profile. Two buttons are available for selection; Start and Cycle Advance. Start - Starts the profile. After clicking on the Start button it will change to a Stop button. Clicking on the Stop button will abort the profile. Cycle Advance - allows the end user to cycle to the next zone. While the profile is running the user can change the temperatures in each zone by using the Click and Drag method described on pages 29 and 30 of this User Guide. Once the profile has been completed click Next. As prompted, raise the head to the home position by pressing the up action buttons. Save the process in the desired location. www.okinternational.com Page 50 of 124 7000-1850, Rev. C

After saving the process you will be taken back to the home page. The New Placement Process is now complete. The previous section described how to develop a New Placement Process using the Component pick up method. The following section will describe the remaining pick up methods; Pickup with Paste; Pickup with Flux Dip; and the use of a Tape Feeder. Pickup with Paste Pickup with Paste is identical to Component Pickup except instead of being placed in the adjustable centering nest the component will be placed in an OK International component stenciling plate and stenciled with solder paste. The stenciling plate replaces the adjustable centering nest. OK International component stenciling plates are optional accessories. Contact Technical support at support@okinternational.com for more information. Solder Paste Application using the Component Stenciling Templates: Select the correct solder paste plate for your component and application. Position the component onto the component side of the plate (the side with the smaller cut out or etched component corners.) Secure the component with the supplied clamp assembly. Be careful not to overtighten the clamp as this can cause the plate to bend, which will affect stencil quality. Apply solder paste to the solder balls using the supplied spatula. When printing, make sure the stencil face remains clean after your print. This ensures correct solder paste volume. www.okinternational.com Page 51 of 124 7000-1850, Rev. C

Carefully remove the component clamp assembly and position the solder paste plate onto the component pick-up plate aligning it with the two tooling pins. Continue with the New Placement Process. Pickup with flux dip Pickup with flux dip is similar to Component pickup with an additional step. After the component has been lifted from the adjustable centering nest, the nest is removed and replaced with a Dip Transfer Plate (DTP) or a Dip Transfer Block (DTB) that has been filled with gel flux. The component is then lowered and dipped in the gel flux. Dip Transfer Plates and Dip Transfer Blocks are optional accessories contact Technical support at support@okinternational.com for more information. DTP Plate DTB Block www.okinternational.com Page 52 of 124 7000-1850, Rev. C

To use the Pickup with flux dip method, follow the same sequence as described in the New Placement Process until prompted to Select component pickup method. Select Pickup with flux dip and click Next. Follow the same sequence as described in the New placement Process until prompted to Move forward centering fixture, Insert plate and set component pick up height. Place the component in the adjustable centering nest and insert the nest on the centering fixture. Then set the component pickup height as described in the New Placement Process. Click Next to continue. Press the up action buttons to lift the component until the head stops at the home position. Remove the adjustable centering nest from the centering fixture and click Next to continue. Insert the DTP or DTB on the centering fixture. Checking this box allows the user to make additional height adjustments during the Process Run. Use the down action buttons to lower the component into the DTP or DTB, actively dipping the solder balls into the gel flux. Click Next to continue. www.okinternational.com Page 53 of 124 7000-1850, Rev. C

Lift the component from the DTP or DTB by pressing the up action buttons until the head stops at the home position. Remove the DTP or DTB from the centering fixture and push the centering fixture back. Click Next to continue. The next screen will prompt the user to set the zoom and focus of the PCB and component. Complete the remainder of the process as described in the New Placement Process. Note: Flux Dip is recommended for micro-smd components. Dip thickness should be half the height of the solder balls and requires the use of a Dip Transfer Block (DTB). Note: Flux Dip does not always work well with 0201 or smaller chips. For these applications it is recommended to use an alternative flux application method that applies gel flux directly to the PCB. Use feeder to pickup The final pickup option is to pick the component from an optional tape feeder. This option allows the user to pick the component from a tape feeder instead of the adjustable centering nest. Tape feeders are optional accessories. Contact Technical support at support@okinternational.com for more information. www.okinternational.com Page 54 of 124 7000-1850, Rev. C

Install the tape feeder by sliding it over a board holder rail and tightening the thumbscrew. Slide tape feeder over a board holder rail. Tighten thumbscrew Tape feeder installed on machine. www.okinternational.com Page 55 of 124 7000-1850, Rev. C

To use the tape feeder option, follow the same sequence as described in the New Placement Process until prompted to Select component pickup method. Check the Use feeder to pickup check box and click Next. Pull out the camera as prompted. The vision window will zoom in on the tape feeder. Use the camera and motor controls to focus the image of the tape feeder and vacuum cup (nozzle). Use the X/Y adjustments to center the vacuum nozzle with the opening in the tape feeder as shown below. Click Next to continue. www.okinternational.com Page 56 of 124 7000-1850, Rev. C

Return the camera to the home position. Use the down action buttons and motor speed controls to lower the vacuum nozzle until it comes in contact with the component in the tape feeder. Click Next to continue. Press the up action buttons to lift the component from the tape feeder until the head stops at the home position. Pull out the camera as prompted. At the next screen remove the tape feeder and install the PCB to be reworked. Follow the prompts and complete the remainder of the process as described in New Placement Process. Note: The tape feeder can only be used with Component pickup and Pickup with flux dip. The Pickup with paste process is not possible with the tape feeder. www.okinternational.com Page 57 of 124 7000-1850, Rev. C

DEVELOPING PROFILES Inner and outer preheating can be used independently or together within the same profile. Dual stage preheating, when both inner and outer preheaters are used together, is designed for rework applications where higher reflow temperatures, tighter temperature control, and minimized damage to adjacent components are required, as shown in the diagram below. The Large preheater is capable of 1800W and is best used for ramping up the PCB temperature uniformly above the glass transition temperature during the Preheat Zone Z1 and Soak Zone Z2. The glass transition temperature of current PCB substrate material, FR4, is 135 C and new lead free substrate material is 170 C The Small preheater is capable of 900W and is best used for ramping up the temperature of the component or device being reworked during the Ramp Zone Z3 and the Reflow Zone Z4. In dual preheating, it is common to see a higher temperature set point for the bottom heater than the top reflow heater, especially when dual preheating. www.okinternational.com Page 107 of 124 7000-1850, Rev. C

The example below illustrates a typical profile containing 5 zones. The temperatures shown will vary depending on PCB size and thickness. Z1 Z2 Z3 Z4 Z5 www.okinternational.com Page 108 of 124 7000-1850, Rev. C

Dual Preheating Profiling Examples These examples illustrate reduced heating power to the underside of the PCB and allow for focused thermal energy to be placed on the reworked components/devices during ramp and reflow zones. Measure temperature at the solder balls by placing a thermocouple under the chip. Three 36 gauge color-coded thermocouples are included in accessory kit. Drilling into the pads from the underside of the PCB is also an option for inserting thermocouples. For a Medium PCB with 6-8 layers substrate 10 inches by 12 inches (254mm by 350mm) set the profile up as shown in the table. Z1 Z2 Z3 Z4 PREHEAT LARGE 350 C LARGE 350 C SMALL 260 C SMALL 245 C REFLOW MEDIUM 180 C MEDIUM 220 C MEDIUM 255 C MEDIUM 270 C TRANSITION TEMP 120 C -150 C 160 C -190 C 220 C -230 C 240 C -245 C (Transition temperature is depicted as red vertical lines in the profile graph) Observations in Z3: a) The preheater is set at a higher temperature than the reflow heater. b) There is a 10 second lag before the temperature transition occurs. c) The temperature rise is fast after the lag; hence, the temperature set points for both the top and bottom heaters do not need to be set much higher than 255 C. In Z5, select B for maximum cooling. Z1 Z2 Z3 Z4 Z5 www.okinternational.com Page 109 of 124 7000-1850, Rev. C

For a Larger PCB and 90 mill (2.1mm) thick substrate, 12-15 layers, 16 inch by 16 inch (450mm by 450mm), P5 socket set the profile up as shown in the table. Z1 Z2 Z3 Z4 PREHEAT LARGE 340 C LARGE 350 C SMALL 300 C SMALL 270 C REFLOW MEDIUM 150 C MEDIUM 220 C HIGH 250 C HIGH 250 C TRANSITION TEMP 120 c -150 C 160 c -190 C 220 C -230 C 240 C -245 C (Transition temperature is depicted as red vertical lines in the profile graph) Although the time from ambient to 120-150 C is not specified for lead-free rework, it is recommended to use a longer soak time (time in Z2) for a thick PCB. The additional soak time allows temperatures to equalize across the chip and PCB, which will yield in better profile delta. It is recommended to use the transitional temperature of 230 C in Z3 so that Z4 temperatures can be achieved easier and quicker. In Z5, select B for maximum cooling.

SITE PREPARATION Solder Removal: Prepare the site to receive a new component by removing all of the residual solder. This can be accomplished by using an MX-500 Series Rework System with blade cartridge assembly. Employing OK International Smart Heat Technology into your rework process will virtually eliminate the potential of accidentally removing any pads when removing residual solder. This is because OK International patented Smart Heat technology ensures that tip temperature is constantly maintained, regardless of the thermal demand of the assembly that is being reworked. For more information on OK International Smart Heat Technology, please contact your local OK International representative or visit support@okintl.com for more information. The following blade style tips are available for the MX-500 Series Rework System: SMTC-x60 (.410 length) SMTC-x61 (.620 length) SMTC-x62 (.870 length) SMTC-x110 (1.55 length) Please note that x denotes tip temperature. All cartridges are available in 500, 600 and 700 series styles. (5 = 500 F, 0=600 F and 1=700 F). As an option, you can utilize a desoldering system such as the MFR-SDI (with internal vacuum pump) or the MFR-SDX (venturi system that requires shop air). NOTE ON CLEANING: Although isopropyl rubbing alcohol and cotton swab work satisfactory for removing flux residue, it is strongly recommended you contact your solder paste manufacturer for recommendations for cleaning the residue left by their products. SOLDER PASTE DEPOSITION and FLUX APPLICATION Component Stenciling Templates The application of new solder paste or flux directly to the component s solder balls can be accomplished with OK International Component Stenciling Templates. The templates allow the precise application of solder paste without concern for surrounding parts on your PCB. Since the component is pasted rather than the board, operators find this to be a much faster and simpler solution. Please contact your local representative for information and availability. Custom sizes and styles are available. Solder Paste Application using the Component Stenciling Templates: 1. Select the correct solder paste plate for your component and application. 2. Position the component onto the component side of the plate (the side with the smaller cut out or etched component corners.) 3. Secure the component with the supplied clamp assembly. Please be careful not to over-tighten the clamp as this can cause the plate to bend, which will affect print quality. www.okinternational.com Page 117 of 124 7000-1850, Rev. C

4. Apply solder paste to the solder balls using the supplied spatula. When printing, make sure the stencil face remains clean after your print; this ensures correct solder paste volume. 5. Carefully remove the component clamp assembly and position the solder paste plate onto the component pick-up plate aligning it with the two tooling pins. 6. Using the vacuum pipette lift the component from the solder paste plate and continue with your alignment process. Body Recognition Plate Two types of paste deposition plates are available for the APR-5000-DZ: 1. BST -To print on balled devices, balled stencil templates are available. 2. BRP -To print on flat components such as LLP or LGA (Land Grid Array), the body recognition plates are available. This is the only recommended method to rework these components. Type 1 Balled Stencil Plate Type 2 Body Recognition Plate Dip Transfer Plates The application of high viscosity paste flux can be accomplished with OK International Dip Transfer Plates. These plates allow for a simple, controlled application of paste flux to the solder balls of your BGA or CSP component. They are available in many sizes and depths. Please contact your local representative for information and availability. Custom sizes and configurations are available. OK International has pioneered the application of high viscosity paste flux using specialized fixtures to ensure consistent repeatable results. www.okinternational.com Page 118 of 124 7000-1850, Rev. C

1. Select the Dip Transfer Plate that meets your component s requirements for size and depth. 2. Using the supplied spatula fill the cavity with paste flux. Use the spatula to smooth the flux level with the sides of the transfer plate. This ensures a repeatable deposit. 3. Place your component into the component pick up plate and pick it up with the vacuum pipette. 4. Using the micrometers, align the component in the X, Y and Theta axes. 5. Remove the adjustable component fixture and replace it with the flux transfer plate. 6. Follow the screen prompts to lower the component into the flux transfer plate so the solder balls contact the bottom plate of the flux transfer plate. Press UP action buttons to return the component to the focus position. 7. Remove the component pick up plate and inspect the impression left in the flux to ensure all the solder balls have been coated. 8. Check component alignment and adjust as required. 9. Follow the screen prompts, push in the camera and click Next. 10. Place the component as directed by the screen prompts, and continue with the placement process that you have selected.
